Ingredients
  

Chicken fajita filling
  • 1.5 lb chicken breast Sliced thin
  • 2 bell peppers Sliced
  • 1 onion Sliced
  • 3 tbsp oil
  • 2 tbsp fajita seasoning Use half for chicken, half for peppers/onions
Quesadillas
  • 8 flour tortillas Large
  • 3 cup shredded cheese (cheddar and Monterey Jack)
Serving
  • 0.5 cup sour cream For serving
  • 0.5 cup salsa For serving
  • 0.25 cup guacamole For serving
  • 4 lime wedges For serving

Equipment

  • 1 griddle

Method
 

Cook the chicken and fajita vegetables
  1. Heat the Blackstone griddle to medium-high and add the oil. The surface should shimmer lightly.
  2. Season the chicken breast with half the fajita seasoning and cook for 6-7 minutes until done. Stir occasionally so the slices cook evenly.
  3. Add the bell peppers and onion, then sprinkle with the remaining fajita seasoning. Cook for 5-6 minutes until softened and fragrant.
Assemble and melt the quesadillas
  1. Place 4 tortillas on the griddle and layer each with shredded cheese, the chicken-pepper mixture, and more cheese. Keep the filling centered for neat layers.
  2. Top each with a remaining tortilla and cook for 3-4 minutes per side until golden and the cheese is fully melted. Press gently with a spatula so the layers stick.
  3. Cut the quesadillas into wedges and serve immediately. Arrange with sour cream, salsa, guacamole, and lime wedges on the side.

Notes

Pro tip: For the best cheese stretch, keep the griddle at medium-high and don’t overload the center—aim for a thin, even cheese layer that melts before the tortillas over-brown. Store leftovers in an airtight container in the fridge up to 3 days; reheat on the griddle or skillet to re-crisp. Freezing is not recommended due to tortilla texture after thawing. Dietary swap: use shredded dairy-free cheese if you want a vegetarian-style cheese melt, but keep the chicken filling for the fajita flavor.
